BOTTLE CAP Filed July '7, 1952 Patented June 20, 1933 UNITED STATESZALOSOHAN, OI CHICAGO, ILLINOIS BOTTLE CA? Application filed July 7,1982. Serial No. 821,244.

This invention relates to closures for containers and is intendedprimarily for application to medicine bottles but is adapted to beapplied to other containers from which it is desirable to dischargemeasured quantities of material. The object of the invention is toprovide a cap which may be easily manipulated to efiect a discharge of ameasured quantity of the contents of a container and which may beadjusted to prevent release of more than the desired quantity and toprevent ultimate discharge of the material until further flow from thecontainer has been cut ofi. The invention is illustrated in theaccompanying drawing and resides in certain novel features which will behereinafter first fully described and then more particularly defined inthe claims.

In the drawing, Fig. 1 is a view, partly in elevation and partly invertical section, of a portion of a container having my improved cap?applied thereto,

ig. 2 is a horizontal section on the line 2-2 of Fig. 1,

F ig. 3 is a detail perspective view of the measuring tube.

In the drawing, the reference numeral 1 designates a portion of a bottleupon the mouth 2 of which are external ribs or threads, as indicated at3. The cap constructed according to my invention includes a cylindricalouter casing 4 having a closed outer end 5 provided with an opening 6therethrough at some point eccentric to the axis of the cap. The loweropen end of the cap is provided with threads. as indicated at 7. wherebyit may be readily applied to and turned home on the mouth of a bottle orother container. The closed end of the casing 4 has a central openingwhich recelves the upper end of a measuring tube 8 which is of acylindrical form having a closed upper end 9 and of such diameter thatit will fit closely in the central opening of the cap of the measuringtube, an annular bead 10 is formed thereon and a valve disk 11 ismounted upon and secured to the measuring tube immediately above thebead so as to rest on the bead and turn with the tube, and this but mayturn therein. Near the upper end valve disk has an opening 12 formedtherethrough so located and of such form and dimensions that it may, attimes, register with the outlet opening 6 in the cap and thereby permitan outflow of the material which has been admitted to the cap. Themeasuring tube is provided with an opening 13 in its side immediatelybelow the bead 10 and near its lower end a diametrically oppositeopening 14 is formed in the tube, as shown and as will be understood.Secured in any convenient manner within the casing 4 is a partition 15which is so located as to lie just above the mouth of the bottle orother container and entirely out ofi' direct communi- 55 cation betweenthe container and the interior of the cap casing 4. The partition, asshown in Fig. 1, extends to the measuring tube 8 and at its center isformed with a socket or boss 16 which fits closely around the measuringtube, as shown in Fig. 1, and is provided with an opening 17 in its sidewith which, at times, the opening 14 in the tube will register. 7

The use of the device will, it is thought, be readily understood andappreciated from the foregoing description taken in connection with theaccompanying drawing. The container is filled with the medicine or othercommodity and the cap is then applied thereto in the position shown inFig. 1, and it will be noted that in this position the openings 14 and17 are alined while the opening 12 is at the same side of the tube asthe openings 14 and 17 and the opening 6 is covered or closed by thevalve 11. If the container be now tilted without disturbing the positionof the measuring tube and in such manner that the opening 6 will be atthe low side of the cap, 1 the contents of the container will flowthrough to the openings 17 and 14 into the measuring tube and then alongthe tube to pass through the opening 13 and collect in the chamberdefined by the partition 15 and the casing 4. If the container be nowset upright, so much of the commodity as may be within the measuringtube or above the lower side of the opening 13 may flow back to thecontainer but all of the commodity which is below the opening 13 andoutside the measuring tube will 1 passed from be retained in the chamberof the cap and will be supported by the partition 1 5. If the measuringtube be now turned until the opening 12 alines with the opening 6,discharge of the material in the chamber of the ca Wlll. be effectedthrough the openings 12 an 6 in an obvious manner. before returning thecontainer to an upri ht position, the measuring tube be turned t roughone quarter of a revolution none of the commodity which has thecontainer will be ermitted to return thereto and then, when t e tube isgiven a further quarter turn, the entire quantity of the commodity whichmay have passed into the chamber of the cap will flow through the alinedopenings 12 and 6.

The device is exceedingly simple in construction and neat in appearanceand effective in operation. It may be very easily applied to or removedfrom any container and While it is designed primarily for use u onbottles of medicine it may be em loye to prevent wasteful discharge ofdenti rice from its container or for delivering measured quantities ofother materials. All of the parts of the device may be stamped fromsheet metal so that it may be produced rapidly and cheaply, and thepartition may be easily secured in the cap by soldering or brazing andthe boss or socket on the particylindrical cap having its inner end adated to fit about the mouth of a container an its outer end provided withan eccentric discharge opening and a concentric opening, a measurin tubehaving its upper end fitted throu h t e central opening of the cap andprovi ed within the cap with diametrically opposite openings adjacentits opposite ends, a valve disk carried by the measuring tube above theupper opening therein and having an eccentric opening adapted at timesto aline with the eccentric opening in the cap, and a partition securedwithin the cap and arranged to extend over the mouth of the containerand provided with a central socket fitting closely around the lower endof the measuring tube and provided in its side with an opening adaptedto at times aline with the lower openings in the measuring tube. 1
